IMPROVEMENT IN NOZZLE FOR CANS. y

The Schedule referred toin these Letters Patent and making part of the same To all whom 'it may concern:

Be it known that I, CHARLES PRATT, of the city, county, and State of New York, have invented a new and useful Improvement in Nozzles for Sheet-Metal Cans; and I do hereby declare the following to be a full, clear, and exact description thereof', which will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which ythe ligure is a perspective view of a sheet-metal can, showing my improvement applied thereto, part of the nozzle being broken away.

My invention has for its object to produce au improved sealfor the nozzles of sheet-metal cans, such as are used for the transportation of certain brands of burning oils and other fluids, which, when removedl from the nozzle, will leave evidence of its having been used.

It has heretofore been customary to seal the nozzles of sheet-metal cans by first placing a cork in the nozzle, and then covering it with sealing-wai( 'containing the impression of the dealers name and the character of the oil, but thismethod is expensive, and does not leave any trace, when removed, -by which the brand of the oil may be determined. Neither does it furnish any distinguishing marks, when in the market, by which the superior oils may be separated from those of inferior quality.

My invention is designed to obviate these dilculties, and to this end, it consists in soldering a thin .sheetmetal cap, upon which the name of the dealer, or the quality of the oilihay be stamped, to the upper edge of the nozzle, in such a manner that when cut from the same, a narrow band or strip of metal shall be left, by

vwhich the cans can be readily identified, as containing certain brands of oils.

In the drawingsp A is a sheet-metal can, of suitable dimensions, and

B is the nozzle, secured to the same, with its upper edge-turned over and wired, in the usual manner.

Gis a thin sheet-metal cap, struck up, as shown, with a curved edge, or flange, c, with a narrow shoulder, b, between said flange and the top c.

If desired, the brand of the article contained in the can, or the name of the dealer, or both, may be stamped upon the top c.

The cap O is applied to the nozzle by fitting the curved liange a over the bead d of the same, and soldering it in place.

`The flange must extend sufficiently down upon the bead to remove the solder from the shoulder a, and to leave the bead with a smooth upper surface, when the cap is removed.

This is accomplished by cutting, with a knife, or other sharp instrument, along the shoulder a, the bead d furnishing a guide and bearing-surface for vthe knife.

It will be observed that the point of soldering is so far below the shoulder a, that only the soft metal of the cap will be encountered by the knife, and that therefore, the cutting operation can be performed with the utmost ease and expedition.

By the removal of the cap in this manner, the flange is left upon the nozzle as a means for identifying the quality of oil contained in the can, and is so far below the upper surface of the bcaddas to allow unobstructed passage for the oil in being poured from the can, and so as not to interfere with the introduction of a cork tothe nozzle.

Myinvention is simple in construction, easily applied tcans, and satisfies a need long felt in the market.

The nozzle I desire to provide with a flange at the bottom, by which it may be attached to a can, so as to he placed in the market indepcndentlypf the can, as

an improved nozzle and seal for different kinds of goods.

' Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

As a new article of manufacture, a nozzle for sheetmetal cans, provided with astruck cap, C, of soft metal, having a curved flange, a, and cutting-shoulder b,s11b stantially as described for the purpose specified.

To the above specification of my improvement I have set my hand, this 16th day of February, 1869.

CHAS. PRATT.
